GFF ICE LIQUID FUEL RANGE Lee S. Chadwick, Shaker Heights, Ohio, assignor to Perfection Stove Company,Clevelan'd, Ohio,

a corporation of Ohio Application Ma s, 1938, :senaljm. 206,398 11 Claims. (01.126-44) This invention relates to oil burning stoves or Lranges used for cooking and baking. i

.H'eretofore, in such apparatus, the oven has "occupied a position above the plane of the stove .top-an arrangement considered necessary to enable the oven burners to be reached with reasonable ease for cleaning, lighting and adjusti-ng purposes.

The main object of, this invention is the production of an oil burning cooking stove or range [of the so-called table-top variety wherein the oven is below the plane of the stove top and which is characterized by a movable. and desirably removable, burner unit for heating the oven, the

name being shiftablebetween an operative position beneath the oven'and a second position laterally or forwardly thereof. i

Another object is to include in such a stove or range an open front burner compartment below the oven, provided With a downwardly opening door onto which the burnerunit may be shifted. when the door is open, and desirably from which the unit may be lifted so that it may be carried to a more suitable place and supported at a more convenient elevation for cleaning.

' A further object is to provide a track ;in said compartment, and an extension thereof on said door, so that when the door is open the extension constitutes, in effect, a continuation of the track along which the unit is readily slidable between a position beneath the oven and. a position upon the door.

A still further object is to include in the structure a second compartment alongside the burner compartment separated therefrom by a partition, and to provide a burner-unit from one side of which extends a conduit that supports a fuel reservoir in spaced relation to the unit so that the unit may occupy the burner compartment while the reservoir is situated in the other compartment, the aforesaid partition having aforwardly opening notch for the accommodation of said conduit. g

Another broad object of the invention is to provide, in a table-top stove or range wherein the space for the cooking burners and the oven are located side by side below the stove top, means for disposing of theproducts of combustion from the oven burners in such manner that they will have no efiect upon the action of the cooking fburners. v i g Additional objects and advantages will appear as this description proceeds, reference being had to the accompanying drawings wherein Fig. ,1 is a perspective view of the stove arrange of my in- :vention with the oven :burnerunit .removedyFig. 2 is a similar yiew of said burner unit; Fig.3 is a fragmentary ..sectional side elevation of the stove on a scale considerably enlarged over that of the previous views, the plane .of section being indicated byithe line -33 of Fig; 5, and the burner through which the plane of section extends being shown in elevation; Fig. 4 is a fragmentary sectional plan substantially on the line 4-4 of Fig. 3, the burner unit being omitted ex- JD cept as indicated .j'in dot-and-dash lines on the track extension of the door; Fig. 5 is a, vertical section substantially on the line 5-5 of Fig. 3.; Fig. 6 is a bottom plan view of the oven burner unit, and Figs. 7 and 8 are atront elevation and an end elevation, respectively, of the stove, each being partlyin section.

The frame of the stove comprises a top I, ends 2 and 3, and a base I, all suitably connected together. The frame is supported at its four cor- ,20 ers by legs .5. A vertical partition 8 extends from the top Ito the base A, somewhat to the right of the longitudinal center of the structure as the sameis viewed from the front, and said partition is approximately the same in width ,5 5 from fronttoback as the base 4. .Ahorizontally disposed burner plate or bailie Ill defines the bottom of a space designated .152 that encloses the upper ends of the cooking burners and their drums or chimneys, oneof such burners being .30 shown at IS in Fig. 7, the drum or chimney whereof is designated II. This portion of the structure constitutesno part of my present invention and is disclosed and claimed in an earlier patent to Charles J. .Kessler and myself, No. "2,068,122, dated JanuarylQ, 1937. Oil is supplied "to the 'cooking'burners through a pipe that leads from anoil reservoir (not shown), access to which is had through an opening in the stove top, normally closed by a door 16. The cooking burners are situated below an opening in the stove top thatis equipped with a :grid l8. The top of the grid "is substantially flush with the portion 19 of the stove top that is over the oven, .so that *vessels may be slid from one .to the other; and an apron r20 .rises from the rear edge of the stove top and is coextensivev in length therewith.

Carried by the partition 8 and end 3 are air ducts .25 and "2.6, respectively, the same .being closed at their .forward ends and open at their rear ends. Supported .by the ducts '25 and 26 are the bottom. wall 21, .side linings 2B and 29 Landrearlining 30 of the oven that .is designated .generally'hythe (numeral '31.. "The linings 2'8 and 29 are substantially parallel to and are spaced .55

from the partition 8 and end 3, respectively, thereby to provide passageways 32 and 33, while the rear lining 39 bears a similar relation to the oven back 34 so as to provide a passageway 35. The back 34 extends from the stove top I to the plane of the ducts and 26. The passageways 32 and 33 communicate adjacent their up per ends with the interior of the oven through perforations 38 in the linings 28 and 29, and at their lower ends they open into the ducts 25 and 26 through slots provided by the spacing of the upwardly flanged top walls of said ducts from" The rear li ning 30 the partition 8 and end 3. has perforations 4i! near its top, while the oven back 34 is provided with aseries'of holes 4| near its lower edge. A flue like member or shield 42 is attached'to the back of the structure in the ducts 25 and 26.

products of combustionfromi the oven burners enter; the oven. The products rising within the oven .escape through theperforations 38 and to the passageways 32, 33' and 35, those entering the passageways-32 and 33 descending to the ducts 25 and 26 by which they are carried rearwardly and are discharged into the flue provided- 'by the shield 42,'along with the products that escape from the passageway 35 through the holes 4|. It is clear that by disposing of those products that are entrained down the side of the oven adjacent the space 12 in the manner described, they will be prevented from having any effect upon the action of the cooking burners l3. This would not be the case if the more common practice were pursued of perforatingthe side wall of the oven (which, in the present instance, is the partition 8) in aboutthe plane of the holes 4! of the oven back. The employment [of the flue 2 6 obviates the need of similarly perforating the end 3, which would be objectionable from the standpoint of appearance. Doors and 46 close :the open fronts of the burner space'l2 andvoven 3 I respectively, and they are hingedly connected adjacent their lower edges to'theframe structure.

. Belowthe oven is the oven burner compartment 5B, and separated therefrom by the lower portion of the partition 8 is a compartment 5!.

The .lower front corner of the partition 8 is cut away to provide aforwardlybpening notch 52 for a purpose that will presently appear. Applied to the base 4 ji,mn ediatelytb the right of the par- ,tition 8, astheparts are viewedj from the front,

is a channelrnember 53. Extending forwardly and downwardly from the sides-01f said mem her are hangers 54 whose'outer ends are substantially in transverse .alignmentwith the corresponding ends of hangers 55 that are carried by the'ends of the frame structure. Hingedly connected to these hangers 54-and 55 are doors 56 and 5Tfor closing' the open fronts of the compartments 50 and 5l,-'respe'ctively The hinge parts of the doors'involveelements 60 that incorporate rearwardly extending arms, those 10- 'cated at the adjacent cornersof the doors 56 and 51 entering the channel member '53 and being arranged to engage the web thereof to 'stop' the downward swing of the'doors as the doors assume substantially horizontal'position. The arms of the end elements 60 similarly cooperate with parts adjacent the endsof thestructure, and the ,base 4 is provided with openings'th'roughwhich the arms swing. when the doors arej'closedQone 'ofsucIi'openingS bei'ng' shownat""63 in' Fig.4.

15 and 16 respectively.

As is common in stove structures of this character, springs are employed to retain the doors closed and to counterbalance them as they swing downward to open position. Such a spring is shown at 65 in Figs. 1, 4 and 5, the rear end of the spring being anchored to the stove structure while its forward end is connected to a link 66 that is pivoted at 61 to the adjacent element 60. A shallowback panel l0 rises from the base 4 at the rear of the compartments 50 and 5|;

Within the burner compartment 50 is a track consisting of rails 15 and 16, the latter being formed by one of the base flanges of the member .member 55, while a similar guide for the rail 15 is formed by a vertical flange 11. region of theholes 4i and the rearendsof the The oven bottom 2'l,has openings 44 adjacent its edgesthrougnwhich "the effect, continuations of the rails; 15 and 16,.and

they are provided with vertical flanges or guides The rails 15 and 16 are connected to and spaced from the door by trestles 18, the same being of an elevation to dispose the rails 15 and '16 in approximately 'thehorizontal plane of the rails 15 and 16 when the door 56 is fully open. All of said rails are desirably provided with relatively small transversely disposed ridges 19, the purpose of which is to reduce the friction between the burner unit and track, as will presently appear, and the rails on the door are provided with stops 89 at their forward ends, and those within the compartment 50, with rear stops 8|, to limit the sliding movement of and locate said unit. The adjacent ends of the aligned rails are turned downwardly, while the upper edges of the guides 15 and 16 are flared outwardly along their upper edges and at their rear ends.

'The oven burner unit, shown in perspective in Fig. 2, comprises a base or housing that is constructed of sheet metal to provide a horizontal wall 86, front and rear flanges 8'1, and relatively deep side walls or flanges 88'. To the front left corner of the housing 85 is attached a handle 89. The horizontal wall 86 has openings 90. surrounded by upstanding flanges or collars 9|, centrally within which are disposed the burners 92,

burners; andto sustain them in rearwardly tiltedposition are drum rests that are inclined upwardly and rearwardly from the wall 86 immediately back of the collars 9|. The burners 92 are of a common and well'known type and incorporate wick adjusting spindles 96 having hand wheels 91 by which theymay turned. ,The

hand wheel I of the more rearwardly disposed burner occupies a socket 98 on the rear end of a shaft 99 that is rotatably supported by a bracket IOU carried by the housing 85. A hand wheel. ID!

is secured to the forward end. oftheshaft 99.

' Supported within the housing 85 a suitable distance below and parallel with the top wall 86 is a supply pipe I05, formed to provide parallel branches that extend transversely beneath the burners 92.

tened to the adjacent side wall 88 of the hous- The burners are suitably fastened to the pipe, and communicate therewith through ing. The end of the rear branch of the pipe is sealed and similarly connected to the opposed side wall 88 while the front branch is extended through an opening in thelast-ment'ion'ed side wall and projectsa substantial distance therebeyond where it has secured to it a cup-like receptacle H into which the pipe opens. A fuel reservoir Ill, in the present instanceconsisting of a glass bottle,is adapted to be supportedin inverted position by and above the receptacle with itsmouth liquid sealed'therein atanelevatidn that determines thefuel level in the burners 92-, the mouth of the reservoir being equ'i-pped with r a suitable valve that is [automatically open-ed when the reservoir assumes operative position over the receptacle; This is in accordance with common practice.

That portion of "the stove base l'that forms the bottom-walhof the ovenburner compartment 50 is provided with a liberal number'of openings to insure an ample air supply for the burners. Two ofthe openings, which arerelatively large, are located directly beneath the burners when the'burner unit occupies normal position within the compartment, and i said openings are surrounded by flanges H4. Occupying these flanged openings are drip basins I Hi whose peripheral walls are provided with holes H5. The basins are removably supported within the openings by their flared upper-ends resting upon the flanges H4, and their purpose is to catch any oil or char that drops from the burners 92. Within the portion of the stove base d that constitutes the bottom wall of the compartment 5! is formed an annular-sump H8 which serves to collect and retainany fuel. that drops from the receptacle Ill) or reservoir Ill, when the burner unit is in normal position. A hole that occupies the center of the sump l I8 is surrounded by an upstandingfiange -I I9. To better insulate the fuel reservoir from the heat of the oven burners, a shield 6253, in the form of a plate, is attached to and spaced from the partition .8

in the region of the reservoir.

When it is desired to light the oven burners the door 55 is opened and the drums 93-are'tilt- .ed back against the rests 95 andwailighted match or taper is applied to the wicks, after which the drums are returned to .their upright positions on the burners. The wicks of the burners may now be adjusted by the wick adjusting spindles, that of the rear burner being manipulated through the shaft 99, and when this is accomplished, the door 56 may be closed. If a fresh supply of fuel is needed, the door 51 is opened and the empty reservoir HI is replaced by a full one. Should an individual find it at all awkward or inconvenient to light the burners or replenish the oil supply in the manner described, both doors 56 and 51 may be lowered to horizontal position and, grasping the handle 89, the individual may slide the burner unit from the compartment onto the track extension on the door 56. For cleaning purposes, the burner unit should be slid to the front of the track extension, where its movement is arrested by the stops 80, and, if

desired, the unit may be lifted bodily from the ing the door substantially horizontal :when open,

a track located within the burner compartment, a track extension on the inner side of the door that constitutes, in effect, a continuation of the track whenthe door is open, the track and track 5 extension each consisting of laterally spaced parallel rails and vertical guides along the outer sides of saidrails, the adjacent ends of the rails .of thetrack and track extension being inclined downwardly as they approach each other while 10 the corresponding ends of the guides are flared outwardly, and a burner unitrslidable on the track and track extension.
